Preparação de derivados de β-glicosidase por imobilização em suportes sólidos derivatizados
(Universidade Federal de São Carlos, 2011-02-25)
B-glucosidase (BG) is an important enzyme for several biotechnological applications. This enzyme plays an important role in hydrolyses of lignocellulosic biomass in order to produce second generation ethanol (2G ethanol). ...
Dinâmica, otimização e controle de processos de fermentação em estado sólido : desenvolvimento de metodologias em escala laboratorial
(Universidade Federal de São Carlos, 2016-05-04)
Solid-state fermentation is characterized by the growth of microorganisms in absence of free
water. In one hand, it is advantageous because simulates their natural environment, enabling
the use of agro industrial residues ...
Estudo da cinética e do equilíbrio da adsorção da cefamicina C em resina de troca iônica e simulação do processo contínuo
(Universidade Federal de São Carlos, 2011-03-01)
The cephamycin C (CefC) is a beta-lactam antibiotic produced from submerged and aerated cultures of Streptomyces clavuligerus. Acts as inhibitor of cell wall formation of Gram-negative bacteria and is resistant to the ...
Produção de ácido clavulânico por Streptomyces clavuligerus em cultivos em batelada e batelada alimentada com pulsos de glicerol sob diferentes condições de temperatura
(Universidade Federal de São Carlos, 2010-03-25)
The production of enzymes β-lactamases by pathogenic bacteria is the most common mechanism of resistance to β-lactam antibiotics. The β-lactamases catalyze the hydrolysis of β-lactam ring, splitting the ...
